Economist, author and political commentator Robert Reich appeared on "Conan" on Monday night and discussed the ongoing issue of wealth inequality in the United States. He explained to host Conan O'Brien that the country currently has the widest gap between rich and poor of any nation outside of the developing world.

"It is a critically important topic," Reich said, "the widening inequality of wealth, income and opportunity in this country. You know, we are now more unequal than any other advanced economy. We're more unequal that we've ever been in a hundred years, and people aren't paying attention to it."

He went on to say that the director of the new film "Injustice for All," Jacob Kornbluth, approached him and asked if he would like to participate in the making of the film, which won the U.S. Documentary Special Jury Award for Achievement in Filmmaking at the 2013 Sundance Film Festival.

"Lookit, Conan," Reich said, "I'm not a class warrior. I'm a class worrier. I'm worried about what's happening in this society and we're not paying enough attention to it and the problem is that there's no way for this economy to function when the vast majority of the middle class -- and everybody who wants to join the middle class -- doesn't have enough money to buy all the things that the economy is capable of producing."
